The Rauma is a river that runs through Romsdalen, a valley in Møre og Romsdal and Innlandet counties in Norway.

The river was once famous for its salmon-fishing, but since an infection with Gyrodactylus salaris only 5 to 10% of the original stock survives.

The salmon runs up to the Slettafossen, a 16-metre (52 ft) high combination of waterfalls and rapids more than 42 kilometres (26 mi) upriver from the estuary.

The Reinheimen National Park and the Trollveggen cliff are both located along the southwestern shores of the river through the municipality of Rauma.

The Rauma was classified as a protected watercourse in 1992, and the only main tributary affected by hydroelectric power is the Verma River with the over 300-metre (980 ft) Vermafossen falls.
